Title: X-ray generating device
Inventor: MORIGUCHI YUSUKE
IPC: H01J35/14
Filed: 1987-04-17
Abstract: PURPOSE:To make it possible to flatten dosage of an X-ray when X-ray energy changes by providing with a polarizing means to polarize an incident angle of an electron beam applied on a target. CONSTITUTION:If an electron beam 1 is sent to a current coil 5 which generates a line of magnetic force lx, the electron beam 1 is polarized by the line of magnetic force lx, and an X-ray 4 of a dosage rate distribution for which an incident position on a target 2 is deflected in the Y direction is generated. If current is sent to a coil 6, a line of magnetic force in the Y direction is generated, and the incident position of the electron beam 1 on the target 2 is deflected in the X direction and the dosage rate distribution is also deflected. If current values to be sent to the coils 5, 6 are changed so as to change the position of the electron beam 1 on the target 2 in the direction of the arrow in a curve C by time, then, though the dosage rate per pulse is not flat, it becomes flat by moving from a point A to a point B.

Title: Refuse incinerating method
Inventor: PICHAT PHILIPPE
IPC: C02F11/10
Filed: 1991-04-02
Abstract: PURPOSE: To fix pollutant by crushing solid materials, adding liquid waste to the crushed materials to obtain a pasty mass, adding pulverulent calcium carbonate, silicium oxide and aluminum and iron oxides to the pasty mass, and incinerating the mixed mass. CONSTITUTION: The solid portions of waste materials are crushed and ground to a granulometry of under 5 mm. After the addition, if applicable, of liquid waste to the granulometry to obtain a pasty mass, an additional material consisting of pulverulent calcium carbonate, silicium oxide and, possibly, aluminum and iron oxides having under 50 μm average particle size is added to the pasty mass to be incinerated at about 750 deg.C to 1350 deg.C. The additional material is changed depending on the type and character of waste materials to be incinerated and a concentration of the final effluent is adjusted to formula I. Thus, high endothermal reaction is occurred by deoxidizing limestone with the inexpensive additional material in the waste incineration treatment to combust a larger amount of wastes at a lower temperature. The burnt residue is insoluble and inert solids.

IPC: B01J19/00
Filed: 1984-05-12
Abstract: PURPOSE:To reduce the heat stress of a temp. variation responsive region, by forming a large number of notches to a surface receiving temp. fluctuation. CONSTITUTION:A large number of notches 12 are formed to the temp. variation responsive region, of which the thermal expansion changes by temp. fluctuation, occupying the surface region 11 of a heat receiving structure 6.

In usual, when the width D of the notch is 1-2mm. and the depth (h) thereof is 5mm., each notch interval P is set to about 12mm. and the shape of a notch leading end is set to a circular or oval one. By the above mentioned structure, a generally used material such as austenite stainless steel can be used and, even if said material receives temp. fluctuation of large temp. difference, it shows excellent characteristics to fatigue damage.

Title: Equal-speed ball joint
Inventor: YAMAMOTO TOSHIAKI
IPC: F16D3/2245
Filed: 1982-06-07
Abstract: PURPOSE:To prevent the outer race from damage or wear, by angles of contact between the ball and the ball rolling groove in the outer race, depending upon the position whether it is the center of the ball rolling groove or the front or the rear of the center. CONSTITUTION:Angles of contact theta1-theta3 between the ball 2 and the ball rolling groove 3 in the outer race 1 are adapted so that both the angles of contact at the front and at the rear of the center of the ball rolling groove 3 are smaller than that in the center, and therefore the ellipse of contact between the ball 2 and the ball rolling groove 3 is kept from going outside the groove 3. Accordingly, the ball 2 does not ride on the shoulder portion of the ball rolling groove 3, and the outer race 1 is prevented from damage. The equall-speed ball joint with durability has thus become obtainable.

Abstract: PURPOSE:To prevent the human errors of transmission by storing the dial number of the transmission inhibited destination and the transmission inhibited time band with correspondence secured between them and then displaying these dial number and time band if it is decided that the transmission is inhibited for the dial number to be operated. CONSTITUTION:When a key 82 is selected in a transmission control state through a control panel 12, an MPU 4 controls the transmission of a facsimile equipment based on the transmission control program stored in a ROM 6. The area code and the overseas station number to be controlled are stored in a RAM 8 together with the transmission control time corresponding in 1:1 to each of both numbers by means of the ten keys 81 of the panel 12. Then the area code and the overseas station number corresponding to the FAX number of the transmitting destination are inputted via the keys 81 and compared with the station numbers stored in the RAM 8 respectively. If the coincidence is secured between both numbers, the control time band is compared with the transmission time for decision of the transmission control. Thus the transmission is discontinued. If not, the MPU 4 controls the transmission/reception of the facsimile equipment based on the control program stored in a ROM 5.
